1929, when the Warsaw Convention containing certain rules 
relating to international carriage by air was drafted, charter ope 
rations were very rare in the field of aviation. The question of the 
applicability of the Warsaw Rules  to air charter was therefore 
intentionally left open.  Nowadays charter operations form a sub 
stantial part of air transportation. Thus, we  are now forced to 
seek a solution of the important problem whether or not the War 
saw Rules are applicable to air charter agreements. 
In this book, the problem of interpretation just mentioned has 
for the first time been discussed in detail. The book may be useful 
for all those who are interested in air law or engaged in air charter 
operations. It may also be of current interest from an international 
legislative point of view, as the problems concerning hire and char 
ter of aircraft are now on  the agenda of the Legal Committee 
of ICAO.

PREFACE 
This study deals with a problem which is of practical im 
portance chiefly to air carriers and may therefore seem  to 
be highly specialized. But it may also be looked upon as a 
modest  contribution  to  one  particular aspect  of  an ever 
fascinating  general  problem  in  legal  theory-that  of  the 
effect of mandatory rules. 
Much of the material was collected during a stay in the 
spring of  1954  at the  Institute of International Air Law, 
McGill University, Montreal. My research work in this world 
center of civil aviation organization was made possible mainly 
thanks to an invitation by Professor John Cobb Cooper, who 
was then the Director of the Institute. I should like in this 
place to express my gratitude to Professor Cooper for  the 
kind and generous interest he has taken in my work. 
I also want to acknowledge the generosity of the Sweden 
America Foundation, as well as of the Edvard Cassel Founda 
tion, University of Stockholm. 
For inspiring discussions and valuable information I  am 
much indebted to several foreign experts in air law and to 
a number of Swedish friends.

INTRODUCTION 
In 1929, when the Warsaw Convention containing certain 
rules relating to international carriage by airl was drafted, 
the type of contract known as charter contract (charter agree 
ment) was very rare in the field of aviation. Although the 
question as  to  the  applicability of  the Convention  to air 
charter was raised at the Warsaw Conference, it was inten 
tionally left open.2  The reason was  that charter operations 
were not yet sufficiently developed and clarified. Since that 
time the situation has completely changed. Nowadays charter 
operations form a substantial part of air transportation and 
they show an increasing tendency to become more important. 
One result of this evolution is  that we  now are forced
